This is a summary of my lectures during the 2011 IAC Winter School in Puerto de la Cruz. I give an introduction to the field of stellar populations in galaxies, and highlight some new results. Since the title of the Winter School was {\it Secular Evolution of Galaxies} I mostly concentrate on nearby galaxies, which are best suited to study this theme ...

The Average Stellar Population Age and Metallicity of Intermediate-redshift Quiescent Galaxies
The HectoMAP spectroscopic survey provides a unique mass-limited sample of more than 35,000 quiescent galaxies ( D _n 4000 > 1.5) covering the redshift range 0.2 10 ^11 M _⊙ ) assemble the bulk of their stars at earlier epochs.

Stellar Collisions in the Galactic Center: Massive Stars, Collision Remnants, and Missing Red Giants
Like most galaxies, the Milky Way harbors a supermassive black hole (SMBH) at its center, surrounded by a nuclear star cluster. In this dense star cluster, direct collisions can occur between stars before they evolve off the main sequence.

Do Red Galaxies Form More Stars than Blue Galaxies?
A new model is proposed in which typical galaxies form most of their stellar mass in a phase with an intrinsically red stellar population. In the standard picture, galaxies with intrinsically red stellar populations are believed to have old stellar ...

In NGC 2992, a galaxy-scale ionized gas outflow driven by active galactic nuclei (AGNs) has long been recognized, yet its impact on the host galaxy has remained elusive.

On the complex stellar populations of ancient stellar systems [PDF]
Het bestuderen van oeroude sterren in hedendaagse, nabije sterrenstelsels om hun geschiedenis te reconstrueren valt onder de noemer van stellaire archeologie. In de afgelopen jaren hebben nauwkeurige observaties onthuld dat veel oude sterrensystemen in de buurt van de Melkweg complexer zijn dan daarvoor was aangenomen.

Alpha Element Populations Among Local Halo Stars
Previous studies have shown that the halo of the Milky Way galaxy is made up of two distinct stellar populations, one from dissipative collapse and the other accreted.
